Low Speed Braking Control*
Using sonar sensors located on the front and r ear bumpers, this system can detect if
there is danger of a potential collision with a wall or other obstacle during normal
driving or when the accelerator pedal is depressed with too much force. The system
then assists in avoiding collisions and reducing damage from impact through
assistive braking and/or assistive driving power suppression.1 Low Speed Braking Control*
If the Low Speed Braking Control activates in a
situation where you do not want automatic brake
application (such as when the vehicle is between two
railroad crossing gates), simply press the brake pedal
to deactivate the system and then continue to drive
as intended.
3WARNING
The Low Speed Braking Control System
cannot avoid all collisions and may not
reduce damage in each situation where the
accelerator is mistakenly or aggressively
pressed. Overreliance on the system may
result in a collision with serious injury or
death. Always check your surroundings,
your shift position, and your pedal use.
Driver remains responsible for safely
operating the vehicle.

â– Assistive braking
Assistive braking provides a visual and audible alert when the vehicle is moving
between approximately 1 and 6 mph (2 and 10 km/h) and there is the possibility of
a collision with a detected wall or other obstacles, as well as providing assistance
with braking.
If the only rear sensors are turned off using the parking sensor system, the assistive
braking will not work when reversing.

sensors, please refer to the following page.

The vehicle will release the brake and start moving a
few seconds after the system is activated. To keep the
vehicle stopped, keep the brake pedal depressed or
put the transmission into

In order to prevent the sy stem from activating when
not needed, always turn it off during vehicle
maintenance, when loading on ships, trucks, and so
on, or when using a chas sis dynamometer or free
rollers for inspection or when washing the car in
conveyor type car wash machine.
If you put any accessories on or around the rear
sensors, the Low Speed Br aking Control System may
activate if it detects these accessories as an obstacle.
In this case, turn off the rear sensor. 2 Customized Features P. 376Audible Alert

Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depresse d for approximately four seconds.
• When the brake pedal is depressed.
Conditions for assistive braking cancellation.
• A certain amount of time has passed since activation.
The system may not operate correctly under the following conditions:
â– Examples of obstacles the sonar sensors cannot detect
• Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fenc es, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Obstacles that are not perp endicular to the ground.
• Moving objects or obstacles that suddenly enter the road.
â– Conditions for Cancellation
â– Low Speed Braking Control System Conditions and Limitations
1Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.

Adaptive Cruise Control (ACC) with Low Speed Follow
Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 570
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 568
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Speed Follow only when
driving on expressways or freeways and in
good road and weather conditions.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
When to use
â– Vehicle speed for ACC wi th Low Speed Follow: A vehicle is detected ahead
within ACC with Low Speed Follow range – ACC with Low Speed Follow
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC with
Low Speed Follow operates at the speed of 25 mph (40 km/h) or above.
â– Shift position for ACC with Low Speed Follow: In ( D or .B

Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press the RES/+/SET/− switch up or down when you reach the desired
speed. The moment you release the switch , the set speed is fixed, and ACC with
Low Speed Follow begins.
When you use ACC with Low Sp eed Follow, Straight Driving Assist (a feature of the
Electric Power Steering system) is activated.
By enabling the steering system to automa tically compensate for natural steering
pull, Straight Driv ing Assist makes it easier for you to keep your vehicle in a straight
line.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.

Driving
When a vehicle whose sp eed is slower than
your set speed comes in or cuts in front of you
and is detected by the radar and the camera,
your vehicle starts to slow down.
A vehicle icon appears on the
gauge.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow may start accelerati ng your vehicle under the
following circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC with
Low Speed Follow detecting range. A vehicle detect
beep on and off can be selected. 2 Settings

Driving
â– There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your ve hicle from traveling at
the set speed, ACC with Low Speed Follow
accelerates your vehicle to the set speed, and
then maintains it.
On steep downhill during ACC with Low
Speed Follow, it brakes to inhibit excessive
acceleration for maintaining the set speed.
However, the vehicle speed may become
faster than the set speed.
â– When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alert even if a vehicle is in the ACC with Low Speed Follow range.
ACC with Low Speed Follow stays on unle ss you cancel it. Once you release the
accelerator pedal, the system resume s an appropriate speed for keeping the
following-interval while a vehicle ahead is within the ACC with Low Speed Follow
range.
1 When in Operation
•ACC with Low Speed Follow may temporarily
control the interval between your vehicle and the
vehicle in adjacent lane or surroundings of your
vehicle depending on the road conditions (e.g.,
curves) or vehicle condi tions (e.g., operating the
steering wheel or the vehicle location in the lane).
•When the vehicle ahead of you moves away, such
as when entering an interchange or rest area, ACC
with Low Speed Follow may continue to maintain
the set following-interval for a short time.
A vehicle icon with line contour
appears on the gauge.
